SEGSTLABSURBEE REHZCLE-SPRINGS.

To all whom it may concern:

Be it known that l, lit-Your D. Surname} a citizen of the United States, residing at New Castle, in the county of Lawrence and State of Pennsylvania, have invented certain new and useful Improvements in Shock-Absorbem for l 'ehicle-Springs, of which the following is a specification.

My invention relates to devices ior'ahsorhihg the shookon vehicle springs in passing and has for its object the pl'oj'ision of a dewas that IS effective in operation, simple in tnre,;and that can be applied to vehicle springs of difierent types.

The construction and o )e-rat-ion of my invention will he descrihe in detail hereinafter and illustreted'in the aeeonnianying drawings in whieh Figure l is a View showing my improved shock absorber attached to an elliptic spring,

)late used with the absorber to support the. vehicle in case of a broken spring, Fig. l e cross section on the line ;r-;r of Fig. 3., and Fig. 5, a. cross section on the line i i In the drawings similar reference charm. ters indicate corresponding parts throughout the several views.

My ini roved shock absorber consists of front stee plates 1 secured in wairson thetwo sides of distance plates 2 an 3 and having ing openings or slots 4 therehetween, the ooenin 's or slots between the two sets of plates heing opposite one another. 'lho distunce plate 3. is provided with hole 5 to receive a bolt 6 in securing it to anflzzngle plate 7 secured to the lower half of the elliptic. spring A shown in Fig, l or to the semielliptie spring B shown in Fig. 2 by means oi clips 8.

friction lates consist of metal plates 5) The having their is ges bent upwardly as shown pads 12 that engage the outer surfaeeof plates 1.. The friction plntes'are held against the plates 1 by means of a holt- 13 having a shoulder M'to seat against one of the plates 9 and a threaded end 15 that is inserted the l 'ietion'peds.

16 represents a coil spring interposed he Es'peeificstion of Letters Patent.

It will he understood that h tightening adjusting nut 15 the plates 9 are drawn toward one another so as to spring the plates 1 inwardly. When properly adjusted the friction plates move lreely on the middle of J the plates l but should an ob truction he. eneounteiwl so that thelrietion plains ap-- proach the ends ol' dates 1 the friction increased llllilllrt, oi the lined distanee be tween the sidesol' the plates at their ends and the rebound from the obstruction gradually and oliioienlly absorbed" In. case oi breakage of u. spring the. adjusting nut 15; may he loos ned to allow the dates] lo relax and then a plat:- 32 l. pl ed lwlu'von the plate 1 and tightening not it; so a to see-urelv clamp the purl together. This \villsupporl the vehicle until lhe spring wan be repaired.
